Be it known that` I, AUGUSTYVVOLFF, acitizen of the United States, andresident of the borough of theBronx, countyof the Bronx,

cit),T and State of New York, have invented certainvv new .and usefulImprovements in `Windows, of which therlollowing is a speci- Vfication.y l Y .This invention relates to improvements in windows and`particularly to typesused in ,connection -with window frame structureshaving a curved upper portion and in which the window -sash raisingspace isrestricted.

j -The principal object of' theinvention is to provide atransparent andflexible window pane and sash which may be raised under conditions wherea-rigid pane could notpbe Y' utilized. ,Y

Another objectl isto provide means wherev bythe window paneand its framemay be guided in a curved pathway as it isiraised,

both frame land pane'being of suicient lex- 'y ibility to readily permitofbendinginivthe operation. of raising. H

A stilly further object is to provideastructure .which 'is ysufficientlyflexible' to permit 'it to be bent or curved to a relatively small.,

radius without'fracture;-`y i These and other objects areattained by thenovelconstruction and combination of parts hereinafter described, andshown in the accompanying drawings, forming a materialg'part otthisspecification,` and in whichof a curved -window frame showing. a sashand pane made in accordance with the invention; F'gure 2 is a verticalsectional view thereof, taken on the line 2-,2 of Figure 1;

VFigure 3 is an enlarged fragmentary sectional view taken on line 3 3 ofFigure 1; Figure 4 is a plan view of the window sash' 1 f c F igure 5Vis a transverse vsectional view taken on line 5--5 oLtFigure 4; and

Figure 6` is an enlar ed fragmentary sectional viewta-ken on-"lineG- ofFigure 4.

In a window framehaving a 'curved up.- per ortion, it is oftendes'irableto raise the win ow sash for the purpose of ventilation,

and also for unobstructed observation, butk in these structures, it isimpossible for the sash tofbe raised vertically to a desirable extentbecause of insufficient room there- Figure 1 is a fragmentary frontelevation i aboveV and the curvature frame. v

In order to permit the raising of the sash in a satisfactory manner, itis necessary thatthe window pane and its attached sash be of the windowsuiliciently flexible that it may curve in con-ik ormitywith the vframestructure, which obviouslyv cannot be done with rigid panes such asglass. y p K In the carrying out of this invention, a

flexible `pane 10v is used, made of material i Vto the sash sides 11 andthe bars 12 in any preferred manner, 'as by screws 14 and 15,respectively. Of course, rlvets or other suitable forms oie securingmeans may be employed in place of the screws 14 and 15, if desired. V

The sideelements 11 are suited to enga-ige within'slide-ways 18, formedin the window trame V'curved at their upper portions 19 and formedbetween rigid outer and inner yguides 20 and 21 respectively. Theseguides areconne'cted at the'top by a rigid crossmembefr'23 and at thebottom by a window sill 24, having a plate 25 on whichthe sash frame maybe seated when in a closed position.

An angular flanged bar 27 is provided with lugs or hand grips 26 and is.secured to the bottom member 12 of which bar 27 is a part, acorresponding anged element 28 being a part of the upper memberk12.

` Outer angle bars 30 having vertical portions 31 are secured to the topcross bar 12. A

bar 30 is also secured to the lower part of Athe sash. The screws orrivets 15 pass through the angle bars 27 and 30, cushion elements 32 andplate 10, whereby all the several members are united together.

yExtending outwardly and rearwardly of thesash from the screws 14 arestuds 35,

having semi-'spherical Vends 36 adapted toV operate n in suitably shapedrecesses 40 formed in the outer window guides 20, so that the sash ispositively guided as it is raised or lowered. As will be seen in Figure3, the groove 40 may be formed in an auxiliary plate 41, so

as to accurately guide and maintain the sash in position.

The pane l as shown in Fig. Ll, rispreterably reinforced with pliablewire netting 50, made by weaving longitudinally extending wires andexpanding the spaces therebetween in a well known manner. y

Although the sides ll of the sash are flexible, they are so supported bythe rigid tortion in the plane of the pane `by the engagement of thestuds in the recesses ofthe auxiliarynlate Ll-l. 'From the foregoing, itwill be apparent that the window of this invention may be readily raisedand lowered in its guideways, even though the guide-ways are verysharply curved, and that it will retain its original shape and'conditionafter long-continued use-so that its free movement in its guide-wayswill not be interfered with.

AHaving' thus described my invention and rset `forth the constructionand manner of itsv use, Whatl claim as new, and desire to secure byLetters Patent, is-

1. In a window, the combination of a trame having lateral guide wayscomprising inner and outery members curved at their ,upper portion, oneof said guide members being provided with a longitudinal'recess, andasashhaving aflexible pane, flexible sine bars and substantially rig-idVVIcross bars, one oi said bars having studs lconnected therewith engagingthe recess of ysaid miide ways, and upper and lower angle iron crossbars connected with the first named cross bars. f

2. In a window, the combination of a iframe havinglateral guide wayscomprising inner and outer members curved at their upper portion, one ofsaid guide members being provided with a longitudinal recess, and a sashlhaving a iiexible pane, 'liexible side bars, and substantially rigidcross bars, the side bars having studs connected therewith engaging therecesses ,of said guide ways, and upper and lower angleironcross barsconnected with Vthe tirst named Vcross hars.

In a window, the combination of a frame having lateral guide wayscomprising inner and outer members curved at their upper portion, one ofsaid guide members vbeing provided with a longitudinal recess,

and a sash having a flexible pane, flexible side bars andsubstantially-rigid cross bars, one of said bars having studs connectedtherewith 4'engaging the recesses of said guide ways, and cushioningymembers betweensaid cross bars and pane. y

4.111 a window, the combination of a frame having lateral guide wayscomprising inner and outer membersl curved at l-their upper portion, oneot said 'guide members be-` ingprovided with-Ka longitudinal recess, anda sash having a flexible pane, flexible .side bars and upper and lowersubstantially rigid cross bars, the lower cross bar rvhaving handlits,onel of 'said side lbars havin-g studs engagingv-therecessesrofsaidguide ways, and upper fand lower `angle iron-cross bars connectedwith the first named cross bars.

In'testimonv that 'l claim the foregoing as my invention, I'have signedmy naine' hereunder.
